How many boxed refrigerators fit in a 20ft reefer?
Boxed refrigerators of 700 × 750 × 1,850 mm (also called fridge-freezers in cartons) in a 20-foot refrigerated container (20RF) — inner dimensions 5,444 × 2,294 × 2,276 mm. Calculated by the Cubestow engine on 2026-09-08.
Upright, single layer (not stacked). 72% of the space used, 1 layer high, about 1,890 kg (7% of payload). Open this load in the 3D planner →

The answer in detail
A boxed freestanding fridge-freezer is roughly 700 × 750 × 1,850 mm and 80–100 kg. Manufacturers ship them upright, unstacked, so the answer is a single floor layer — which is why fridges are usually loaded in high cubes with lighter cargo on top of nothing at all.
The refrigeration unit and insulated walls take space, so a reefer is shorter, narrower and lower inside than a dry 20ft. Leave the T-floor and the air return clear.
The simple grid estimate is 7 along the length × 3 across × 1 high = 21. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (21).

Frequently asked
How many boxed refrigerators fit in a 20ft reefer?
21 boxed refrigerators of 700 × 750 × 1,850 mm fit in a 20ft reefer (inner dimensions 5,444 × 2,294 × 2,276 mm), upright, single layer (not stacked). That uses 72% of the 28.4 m³ available and weighs about 1,890 kg.
What are the inner dimensions of a 20ft reefer?
Typical inner dimensions are 5,444 mm long, 2,294 mm wide and 2,276 mm high (214.3 × 90.3 × 89.6 in), giving 28.4 m³ of space and a rated payload of about 27,400 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of boxed refrigerators weigh?
21 × 90 kg ≈ 1,890 kg, which is 7% of the 27,400 kg payload — so this load is limited by space, not weight.
How was this number calculated?
By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing rotation on the floor plane only, no stacking and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.
